Description
The TPT/XF Twisted Pair Transceivers provide a simple, cost-
effective method of adding a L
ON
W
ORKS
transceiver to any Neuron
®
Chip-based control system. The TPT/XF transceivers consist of
transformer-isolated differential Manchester encoded communica-
tion transceivers and connectors for power, the Neuron Chip com-
munications port (CP) lines, and the twisted pair network data bus.
The small size of the transceivers permits them to be mounted
almost anywhere on a printed circuit board assembly, either as a
socketed or soldered component. The TPT/XF transceivers are
available as either a 78kbps transceiver (Models 50010-10 and
50010R-10) or 1.25Mbps transceiver (Models 50020-10 and
50020R-10). The TPT/XF transceivers can communicate with
TP/XF control modules operating at the same bit rate for those
applications using both types of devices.
Models 50010R-10 and 50020R-10 are compliant with the
European Directive 2002/95/EC on the restriction of the use of
certain hazardous substances (RoHS) in electrical and electronic
equipment.
The TPT/XF transceivers use transformers to isolate them from
the twisted pair network bus. This design provides excellent com-
mon mode rejection and permits the system to operate in electrically
noisy environments. It also reduces the susceptibility of the system
to ground loops caused by the use of multiple node power supplies
that float relative to ground. This architecture makes the transceivers
ideal for communicating over long distances in industrial environ-
ments. The transceivers are self-contained network transceivers,
and require only a +5VDC power source, a Neuron 3120
®
Chip or
Neuron 3150
®
Chip and associated memory, an oscillator, and
application electronics to form a complete node.
Using TPT/XF transceivers can save hundreds of hours of
development time compared with designing custom transceivers.
The TPT/XF transceivers are designed to comply with FCC and
VDE requirements, minimizing time consuming and expensive
laboratory transceiver testing. As UL, CSA, and TÜV Recognized
components, the transceivers can be integrated into products with
minimal additional safety testing. The transceivers meet the
L
ON
M
ARK
interoperability guidelines and are economically priced
for OEM applications. In addition, the 78kbps and 1.25Mbps trans-
ceivers fit in the same mounting holes, allowing a common mother-
board to be used with both devices.
Echelon offers a comprehensive range of development tools,
network interfaces, routers, and network service tools to simplify the
task of designing products using the transceivers. Technical support
for the transceivers is available through Echelon’s LonSupport
™
Premier technical assistance program.

Notes:
1. Worst case distance figures are based on variations in node distribution, node temperature, node voltage, wire characteristics, transceiver characteristics, and Neuron Chip
characteristics, and allow for an average wire temperature of up to +55°C.
2. Safety agency hazardous voltage barrier requirements are not supported.
3. For wire specifications, see

4. Proper operation of TPT/XF-1250 segments requires that no more than eight (8) TPT/XF-1250 and/or TP/XF-1250 modules be used in any 16-meter (53 feet) sections of bus
wiring.
